18mm x 1.5
If you need one,I may just have one.
If it is leaking,the common mistake is that crush washers that are used to seal the line to the rear of the engine,and they get lost..so leaky.leaky..(18mm copper crush washers)

Every rotary owner has a 23MM socket in the tool box just for this purpose.

And a (22MM?) wrench ground thinner for the oil cooler line on the front cover.
